Scanning-tunnelling spectra of cuprates

The following abstract is based on this link at Nature an International Weekly Journal of Science

Nature 446, E3-E4 (8 March 2007) doi:10.1038/nature05709; Published online 7 March 2007

Arising from: J. Lee et al. Nature 442, 546–550 (2006)

The study of bosonic modes that couple to the charge carriers is a key element in understanding superconductivity. Using atomic-resolution scanning-tunnelling microscopy (STM) to extract the spectrum of these modes in the high-temperature superconductor Bi2Sr2CaCu2O8+, Lee et al.1 infer a role for lattice modes (phonons). The lattice mode seen by Lee et al.1 is concluded to be irrelevant to superconductivity and is due to inelastic tunnelling through the insulating oxide layer5.

I have read your article but i have to respond to your comment. I understand that many of my 'fundamental' questions were flawed...it was my first blog and i was a little short of rhetorical ideas. I did know about the chlorophyl (secondary education) but i didnt know about the hydrogen bonding..

Thanks for the comment anyway, my friends enjoy it but they cant be bothered to join blogspot...most of them are sporty and like me dont use the internet much.

Your blog is very good however, although i dont quite understand everything, its interesting to read and try to understand something new.

Again... thanks for your good words. My main point to your post was to encourage you and your readers to continue to ask questions. That is what is important. That is how we find answers. As you point out, however, answers are not the end... they are just another beginning :)
